Recently, high‐entropy perovskite oxides (HEPOs) have received increasing interest for energy storage applications owing to their unique structure, huge composition space, and promising properties. However, designing HEPOs with improved energy storage performance remains a challenge. In this study, various HEPOs were designed by partially replacing Zr4+ for Ti4+ in (Bi0.4Ba0.2K0.2Na0.2)TiO3 medium‐entropy ferroelectric ceramics. The resulting ceramics exhibited a pseudo‐cubic structure. With increasing Zr4+ content, the ceramics gradually transformed into relaxor ferroelectrics. The energy storage performance of the ceramics depended on the Zr4+ content. The sample with 20 mol% Zr4+ showed the best energy storage performance with a maximum reversible energy density of 2.47 J/cm3 and an energy storage efficiency of 82.3% at a low applied electric field (224 kV/cm). This study obtained a promising material for the new generation dielectric energy storage capacitors and provided a novel method for enhancing energy storage performance. [ABSTRACT FROM AUTHOR]

To develop nutritional oil similar to Chinese human milk in terms of fatty acids composition and triglyceride, several vegetable oils and 1,3‐dioleoyl‐2‐palmitoylglycerol (OPO) were selected to prepare nutritional oil microcapsule. The result showed that human milk fat substitute (HMFS) prepared by these oils (soybean oil (SO): camellia oil (CMO): high oleic sunflower oil (HOSO): corn oil (CRO): OPO = 28.24:0.00:12.94:8.82:50.00) was the optimal formula. After spray drying, the final microcapsule product was milky white with good solubility and microencapsulation efficiency (MEE = 92.1%). The dispersion coefficient of the microcapsule particle size distribution was 0.200 and the average particle size was 202.767 nm, both particle size distribution experiment and scanning electron microscope (SEM) analysis indicated that the particle size of the microcapsule was uniform and the surface was smooth, After 30 days' accelerated experiment, the peroxide value of microcapsule products was 10.24 meq/kg, indicating the product had good oxidative stability. Practical applications: Human milk is considered the most ideal food source for newborns, but not all cases have human milk for infant. Therefore, it is necessary to produce formula milk powder whose composition and function are closer to human milk. This study used five commonly edible oils and added OPO to develop a HMFS similar to human milk in fatty acids and triglycerides. The optimal formula contributed to long shelf life (27 months) and good physicochemical properties, promoting the development of HMFS. [ABSTRACT FROM AUTHOR]

This review critically evaluates current in vitro gastrointestinal models for assessing infant formulas from a perspective focusing on a process along digestion, absorption and microbial fermentation. Despite their potential, none of the current in vitro gastrointestinal models fully considers the dynamics and continuous upstream‐downstream process of the human digestive tract. Considering the substantial differences between infants and adults, there is a pressing need for whole‐process gastrointestinal models tailored to infants. Developing such models is crucial for accurately assessing infant formula nutritional value and physiological function, enhancing the formulation of infant formulas to better meet the needs of infants.

AbstractDuring the application of Whey proteins (WPs), they often have complex interactions with saccharides (Ss), another important biopolymer in food substrate. The texture and sensory qualities of foods containing WPs and Ss are largely influenced by the interactions of WPs-Ss. Moreover, the combination of WPs and Ss is possible to produce many excellent functional properties including emulsifying properties and thermal stability. However, the interactions between WPs-Ss are complex and susceptible to some processing conditions. In addition, with different interaction ways, they can be applied in different fields. Therefore, the non-covalent interaction mechanisms between WPs-Ss are firstly summarized in detail, including electrostatic interaction, hydrogen bond, hydrophobic interaction, van der Waals force. Furthermore, the existence modes of WPs-Ss are introduced, including complex coacervates, soluble complexes, segregation, and co-solubility. The covalent interactions of WPs-Ss in food applications are often formed by Maillard reaction (dry or wet heat reaction) and occasionally through enzyme induction. Then, two common influencing factors, pH and temperature, on non-covalent/covalent bonds are introduced. Finally, the applications of WPs-Ss complexes and conjugations in improving WP stability, delivery system, and emulsification are described. This review can improve our understanding of the interactions between WPs-Ss and further promote their wider application. [ABSTRACT FROM AUTHOR]

Autophagy-impairment is involved in the pathological process of chronic obstructive pulmonary disease (COPD), and relates to inflammation and emphysema in lung injury. This study aimed to elucidate the protective effect of S -Allylmercapto- N -acetylcysteine (ASSNAC) against COPD via regulating the autophagy. Firstly, porcine pancreatic elastase (PPE)-induced COPD model in A549 cells was established, and ASSNAC was verified to alleviate the autophagy-impairment from the results of western blotting analysis of LC3BⅡ/Ⅰ and monodansylcadaverine (MDC) staining of autophagosome. Secondly, Balb/c mice were stimulated by PPE to induce the COPD model in vivo. The histological analysis of lung tissues presented that ASSNAC could alleviate the lung injury induced by PPE. Thirdly, the secretions of NO, TNF- α and IL-1 β in serum and BALF were reduced by ASSNAC compared with the PPE group. Finally, the mechanism of therapeutic effects of ASSNAC against COPD through regulating the autophagy-impairment was clarified. That is, ASSNAC inhibits the phosphorylation of PI3K/Akt/mTOR signaling pathways. In a word, this research provides a reference for ASSNAC to be an effective drug for pulmonary diseases. • The COPD induced by PPE in mice was ameliorated by a derivative of allicin ASSNAC. • The PPE-induced inflammation and emphysema was alleviated by ASSNAC via regulating autophagy. • The probably mechanisms of ASSNAC against PPE-induced COPD might be associated with PI3K/Akt/mTOR signaling pathway.
